The best land IMO is Frontierland. It's got a fun thrill ride (BTMRR), A great dark ride/ thrill ride (Splash), a fun and family-friendly show (Country Bears). a fun exploration are and playground (TSI), and wonderful theming. It's got everything you could ever want, except maybe a really good restaurant. My favortite is Fantasyland though, but I think in a whole Frontierland is a more well-done area than Fantasyland.
